To Aill whom it may concern: Y j

Be it known that I, WTALTER ZETZMAN, a citizen of the United States, anda resident of Cornelius, in thecountyof Washington and State ofOregonyhafve invented a certain new 4and useful llmprovement in Hoistingand Conveying Apparatus, of which the following'is a specification; Y

The present invention relates to hoisting and conveying apparatus, and`has particular reference to a device adapted for use in barns, stables,andthelike, for transporting and distributing feed,fhay, andv other`ma`terial Vto feed boxes, and other parts of the building, and for variousother uses.`

An object of the "present invention is to provide `a device of thischaracter which is so constructed as to support a carrier box, andprovide for the adjustment ofthe same in the various horizontal angles`beneath the carriage of the device.

The invention also embraces novel means for raising and lowering thecarrier and retaining the same in elevated position while beingconveyed.

'lhe above, and various other objects and advantages ofvthis .inventionwill be in part described and in partunderstood, from the followingdetailed description .of the present preferred embodiment, the samebeing illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of a hoisting and conveying apparatusconstructed according to the present invention.

Fig. 2 is an end elevation of the apparatus in `raised position. V- 0Fig. 3 is a detail enlarged section taken longitudinally andsubstantially centrally through ythe i carrier and the mounted thereon,

Fig. 4 is a transversesection taken substantially `centrallythr'ough thesame.

Referring to these drawings, wherein ylike parts are designated bysimilar characters of reference throughout the several views, 10designates a double rail track, supported in any convenient manner uponhangers` 11 which are adapted for securement to the rafters, or otherportions vof a building in which the apparatus `is `adapted to beemployed. Q

A carriage `12 of hollow construction provided withoutstandingweb'portions at its parts 'directly opposite ends carriesupon said ends a pair 'nf `iupstanding parts or brackets 13 upon$pecication Letters Pat-ent.

the upper -of which are pivotall'y mounted rollersld for engagement`withthe opposed rails of the track 10. The carriage' 12 is preferablyopen at the oppositel ends and provided `intermediate its ends with aratentea nee. a, inra.. applieationmed May 15,1917. serial No. massadownwardly extending hub portion' 151 i through which is verticallyinovable'a pin 16 constituting a trip and bearing at its lower endagainst apair of inwardlyextendl ing lugs formed upon 'the upper pivotedends of thegrip or jaw members 17, thelatter being mounted upon pins 18carried upon the lower end ofthe hub 15.

A `horizontally swingingframe 19 is sup-` ported upon and arrangedbeneath the car rier 12, the same being 'substantially "U- shaped incross section, and connected'to carrier 12 by a tubular bolt orconnecting-mem` ber 20. lThe member 20 is providedat its upper end withan outstanding annular iiange, andV passes downwardly through openingsformedin the adjacent abutting faces of the carriage 12 and the frame19.

Anti-friction bearings 21 are interposed be` tween the lower face of theflange of said member 20, and the upper face of the bottom of thecarriage 12. The lower end of the tubular member 20 is externallythreaded and is provided with a pair 4of interlocking nuts or rings121,the upper one of which is adapted to engage the lowerface of the topwall of the frame 19. The jaws or grip members 17` are relatively lonand project downwardly through thetu ular member 20, and intof-the'frame19. The frame 19 is thus mounted on the lower end of the tubularmember20, and the latter'is freely rotatable inthe carriage 12 by theprovision of'the ball bearings as jshown. that the carriage` `12 isprovided with overhangingweb portions at its opposite ends formedbycutting away the sides1 to admit the uninterrupted turning oftheframe-19 beneath the carriage.

The frame 19 is formed at opposite ends with bracket portions 22 inwhich are mounted for free rotation peripherally grooved rollers 23, andone of the brackets is providedwith a pair of spaced-apart outstanding-arms 24C between the outer vends of'which is mounted a drum 25. Thedrum 25 is keyed upon a shaft 26 which projects at one end beyond theadj acentbracket'arm 24, and which is provided with `afsproeket It willbe noted* leo vit

A fall block 29v is arranged'beneath the frame 19, and is providedtherein with a pair of grooved pulleys 30 adapted to receive'thereunderportions of a fall rope 31 which pass through the lower end of thev itisevident that'the fall rope 31 will be drawn over the pulley 23 andthrough the block 29 to raise the latter. The block 29 is'provided withan upstanding bail 33, having a shoulderedhe'ad 34 adapted for en-Vgagement between-the lower beveled ends of the .jaws 17. The jaws 17 areadapted to swing inwardly toward each other by gravity, and to engagebeneath the shoulder of the head .34s,.thus retaining the fall block inraised position beneaththe frame 19.

A clevisV 35 is pivotally and swivelly mounted upon the lower end of thefall block 29, and is connected, by means of a swivel eye36 to anoutstanding strap or bail A37 carried upon a carrier box or otherreceptacle 38. The box 38 is elongated, is open at'one end, and is heldfrom tilting by the provision of a strap 39 which is secured to theclosed end of the box 38, and which extends to the clevis 35.V

The'track 10 is provided with a tripping block .t0 at any suitable pointwhich lies in the path ofthe tripping pinl 16 and is adapted to depressthe latter upon the movement of the carriage 12 over the track 10.

In operation, when the carrier 38 is lowered, the same may be filled tothe desired `extent, with feed or other material to be distributed andconveyed, and the hand chain 28 is then actuated to rotate the drum 25and wind the fall rope-31 over the same. As the fall rope 31 is woundupon the drum, the fall block 29 is raised in a position be-l neath theframe 19 and when drawn into its'uppermost position, the head 34 of thefall block engages with the`-jaws 17, setting the same apart, and thejaws interlock with the head' to hold the fall block in raised position.The carrier 12 may now be actuated either by gravity, or otherwise, totravel over the track 10 to the desired point of distribution. VWhen thecarrier reaches `the point lof distribution, at which point,

the tripping block 40 is located, the block 10 strikes `the pin16 anddepresses the same to spread apart the jaws 17 and thus release the fallblock 29. The fall block 2 9 being thus released, is drawn downwardly bythe weight of the material within the carrier boX 38. The fall rope 31may be so adjusted as to limit the downward movement of the carrier 38.The hand chain 2S may also be actuated and controlled for lowering thebox 38 to the desired position. A rake or other suitable device may beemployed for withdrawing the contents of the box 38 when the latter isadjusted to the desired psition with respect to feed boxes and the Itwill be particularly noted that the frame 19 may be turned throughsubstantially any angle'about the carriage 12 so as to dispose thehandoperating chain 2S in any desired position, and the carrier 38, byvirtue of its swivel connection with the fall block 29, may be turned topresent its open end at any desired side of the apparatus.

It will also be noted that the apparatus comprises but relatively fewparts, no springs are employed, and the means for locking the fall block29 -in raised position is automatic, and positive.

Itis to be understood that various changes and modifications may be madein the details ofV construction of the above specifically describedhoisting and conveying apparatus, without departing from the spirit ofthe invention, and being restricted only by the scope of the followingclaims.
